Abstract: This application provides a signal detection method and apparatus, and a radar system, which may be applied to the internet of vehicles, intelligent vehicle, autonomous driving, or intelligent driving field. The signal detection method (700) includes: A first radar transmits a first sounding signal in a first time period of a first frame (710). The first radar transmits a second sounding signal in a second time period of the first frame (720). The first radar receives reflected signals corresponding to the first sounding signal and the second sounding signal (730). The first radar determines a false alarm target based on a difference between a first distance-velocity spectrum and a second distance-velocity spectrum (740). The second sounding signal is a signal obtained through first phase code modulation based on the first sounding signal. The signal detection method can be used to determine the false alarm target, and identify a real target, thereby improving a probability and reliability of detecting the correct target.

Abstract: Embodiments of this application disclose a resource scheduling method and a related device, to configure a scheduled resource for a terminal device based on a dynamic analog beam determined by a network device, thereby increasing a throughput of the terminal device. The method in embodiments of this application includes: The network device determines, based on information about an SRS of each first terminal device, a set of second terminal devices from a set of first terminal devices and static analog beam information of each second terminal device in the set of second terminal devices. Then, the network device determines beam domain channel information based on the static analog beam information. Therefore, the network device determines dynamic analog beam information of each second terminal device based on the static analog beam information and the beam domain channel information.
